How to cure bolt stick

Just acquired a 09 slg for cheap, guy says the bolt keeps pinching balls. I took the back part with the Allen key an figured I could push the bolt out with my fingers boy was I wrong. The bolt was so stuck I had to use a sharpie to push it out. Any body else with this problem how did u cure it? I saw one video on YouTube but the kid was polishing the inside of the bolt to cure the stick problem.

Honestly I can say I haven't had an issue with bolt stick out of my 09 but I'm sure it's possible. You should be able to remove the back cap and put your finger in the feedneck and push it out with your finger. I would say to check all of your orings and make sure they are the correct sizes, clean off all of the lube that is on the inside and bolt, and back cap, and relube it with your lube of choice. I use lurker lube and haven't had an issue with it and I personally like it for its slick but sturdy and seems to last a very long time but again it's all personal preference on lube but to each their own. If you do all of that and still have an issue pm me and we can talk more.

I took it apart again the other day and the o ring in the middle of the bolt seemed to be swollen so I replaced it. Lubed it up with the dye grease that came with it. Aired it up today and it shot fine,couldn't shoot too fast all I had was a shake n bake hopper for it for now. I also got bored the other day an tore it down to check out the sear and sear spring. I stretched out the spring just a little just in case while I had it tore down. Seems like my $30.00 investment is gonna make my son a decent first gun.
